Lower Cretaceous of Santa Cruz province, Argentina. Systematic descriptions I: Monolete and smooth and cingulate trilete spores. ( 其他 ). Llorens M. Ameghiniana, 2008, 45(1): 153-166 Smooth and cingulate trilete and monolete disperse spores from the Punta del Barco Formation, Lower Cretaceous of Santa Cruz Province are being described in this paper. The trilete spores belong to the genera Biretisporites, Deltoidospora, Todisporites, Cyathidites, Densoisporites, Foraminisporis, Contignisporites, Laevigatosporites and Reticulosporis. The last genus is mentioned for the first time in Argentina, and is one of the oldest known records. Some of these taxa represent vegetal groups no reported for this taphoflora, enlarging therefore its previous knowledge. 2009020073 阿根廷里奥布兰卡盆地密西西比亚系 Cortaderas 组系统孢粉学研究 : 第一部分 = Systematic palynological study of the Cortaderas Formation, (Mississippian) Rio Blanco Basin, Argentina. Part One. ( 其他 ). Loinaze V P. Ameghiniana, 2008, 45(1): 33- 57 Well preserved Mississippian palynological assemblages have been obtained from the Cortaderas Formation in the Rio Blanco Basin, northwestern Argentina. The geological setting and stratigraphic provenance of the samples is provided. In this first part, fifty-two species are described from a total of seventyeight species of spores recognized. Five new species are proposed: Verrucosisporites incompositus sp. nov., Verrucosisporites perbrevis sp. nov., Anapiculatisporites exiguus sp. nov., Anapiculatisporites expolitus sp. nov. and Dibolisporites insolitus sp. nov. Previous worldwide geographic and stratigraphic records of taxa are detailed. 2009020074 Aquilapollenites 植物地理区系中白垩纪 - 第三纪孢粉植物群的扰动和绝灭 = Cretaceous-Tertiary palynofloral perturbations and extinctions within the Aquilapollenites Phytogeographic Province. ( 英文 ). Sweet A R; Braman D R. Canadian Journal of Earth Sciences, 2001, 38(2): 249-269 A combination of detailed, intermediate and large scale stratigraphic perspectives is necessary to understand the driving mechanisms for floral change across the Cretaceous-Tertiary (K – T) boundary, because short-term physical and biotic events occur within longer term trends. Most Maastrichtian palynofloral extinctions have been identified within the northern circumpolar, supra-continental, Aquilapollenites Province. In mid-continental North America, the presence of a physically defined K – T boundary provides opportunities to examine contemporaneous terrestrial palynofloras over a latitudinal (also approximately paleolatitudinal) distance of 3200 km. Seventy-five percent of last appearances occur before the K–T boundary at high latitudes and must have been caused by ongoing terrestrial processes. Palynofloral events directly associated with the K – T boundary include both local last appearances, and inferred extinctions, and synchronous and diachronous changes in relative abundances. Two different styles of factors are reflected in these events. The first, possibly attributable to chemical or other profound atmospheric perturbations associated with the worldwide distribution of the "fireball" layer of the K–T claystone, resulted in extinctions of angiosperm with a zoophilous pollination strategy. The second factor, possibly reflecting energy released during the deposition of ballistically transported impact debris or hackly (ejecta) layer of the boundary claystone, resulted in the selective, northwardattenuating removal of the canopy vegetation, best documented for southwestern Canada, which was succeeded by a fern-dominated vegetation in mid-continental North America. These consequences of the boundary event were mediated by independent, preexisting circumstances: climate (regional and through time), local depositional environment, and ongoing background extinctions and origins. 2009020075 美国宾西法尼亚州 Allenport 地区志留系剖面的中型孢子和隐孢子 = Miospores and Cryptospores from the Silurian Section at Allenport, Pennsylvania, USA. ( 英文 ). Beck J H; Strother P K. Journal of Paleontology, 2008, 82(5): 857-883 6 图版 . Non-marine and marine palynomorphs were collected from a Telychian through Gorstian rock outcrop located near Allenport, Pennsylvania, USA in the east-central part of the Appalachian Foreland Basin. Close sampling of the section revealed six distinct palynological assemblages of spores, 24
cryptospores, acritarchs and prasinophycean algae, likely deposited in nearshore marine settings. The Silurian Period is a critical time in plant evolution as megafossils found elsewhere indicate that vascular plants (tracheophytes) originated during this interval. Palynoflorules generally show a transition from cryptospore-dominated to miosporedominated assemblages during the latter half of the Silurian. This transition is evident at Allenport, where over 30 species of miospores and cryptospores are recognized, including two new species: Vermiverruspora cottera and Rugosphaera falloambita. The sequential progression of innovations in exine structure and sculpture seen in the nonmarine palynomorphs at Allenport closely matches evolutionary patterns documented previously in the Appalachian Basin, Avalonia, and elsewhere around the world. 2009020076 美国蒙大拿和加拿大西部跨越白垩 - 第三纪界线复合泥岩和相邻地层的连续孢粉序列的变化 = Sequential palynological changes across the composite Cretaceous-Tertiary (K- T) boundary claystone and contiguous strata, western Canada and Montana, U.S.A.. ( 英文 ). Sweet A R; Braman D R; Lerbekmo J F. Canadian Journal of Earth Sciences, 1999, 36(5): 743–768 The boundary claystone in the western Canada Basin is composed of three intimately associated layers with a regional distribution: a basal brownish-grey hackly claystone, a middle brownish-black satiny claystone, and an upper brown laminated shale. These layers appear to represent a graded succession in terms of grain size and depositional rate. An abrupt reduction in the relative abundance of gymnospermous pollen, representing canopy vegetation, immediately precedes the hackly layer. The hackly claystone is accepted as being originally formed of microtektites from a ballistically transported ejecta blanket deposited within minutes or hours of the bolide's impact and associated with a heat pulse. The variable miospore content of the hackly layer is considered to be from local, reproductively active understorey vegetation. The shocked-quartz-rich satiny claystone is interpreted as being formed by fine debris deposited over days, weeks, or months. Its homogeneous texture suggests a short depositional event, but must have involved enough time for a residual Cyathidites- Ulmoideipites survival flora to release miospores. Further, the presence of this flora requires the continuation of light levels required for photosynthesis and temperatures generally above freezing. A settling time of several years for very fine debris and aerosols would fit with the apparent seasonal interlayering of the organic tissue in the laminated shale. The abruptly overlying Laevigatosporites-Kurtzipites recovery flora initiates the succession leading to the return of a canopied swamp, and its presence may signal the clearing of the atmosphere of all impact-generated debris, except for postulated elevated CO 2 abundances. 2009020077 俄罗斯加里宁格勒地区桑比安半岛西部上白垩统和古新统孢粉特征第二部分 = Palynological characteristics of Upper Cretaceous and Paleogene deposits on the west of the Sambian Peninsula (Kaliningrad region), Part 2. ( 英文 ). Aleksandrova G N; Zaporozhets N I. Stratigraphy and Geological Correlation, 2008, 16(5): 528-539 The results of studying dinocysts in the Upper Cretaceous-Lower Paleogene succession of the Kaliningrad region are considered. Distinguished in the succession are seven biostratigraphic units in the rank of the Palaeohystrichophora infusorioides, Chatangiella vnigrii, Cerodinium diebelii, Alisocysta margarita, Deflandrea oebisfeldensis, Areosphaeridium diktyoplokum, and Rhombodinium perforatum beds and one Charlesdowniea clathrata angulosa Zone. The Lyubavas Formation has not been distinguished on the west of the Sambian Peninsula. Ages of the Sambia, Alka, and Prussian formations are verified. 2009020078 俄罗斯西伯利亚西南部陆相渐新世 - 中新世沉积的孢粉地层 = Palynostratigraphy of Oligocene-Miocene continental deposits in Southwestern Siberia. ( 英文 ). Kuzmina O B; Volkova B S. Stratigraphy and Geological Correlation, 2008, 16(5): 540-552 Data on spores, pollen, and dinoflagellate cysts studied in composite section of Oligocene-Miocene deposits in southern part of West Siberia are presented. Eleven biostratigraphic units distinguished in the section are ranked as palynozones and beds with palynological assemblages. Palynological data substantiate age of deposits and specify ranges and boundaries of palynozones. Based on dinocyst assemblages first studied in 25
